Increasing the adoption of conservation agriculture: A framed field experiment in Northern Ghana
通过加纳北部的田野实验，研究了激励和同伴信息如何影响农民采用保护性农业技术，发现激励能提高采用率且效果持续，而关于长期采用和产量收益的信息也有促进作用。
Abstract Conservation agriculture techniques have the potential to increase agricultural production while decreasing CO 2 emissions, yet adoption in the developing world remains low—in part because many years of continuous adoption may be required to realize gains in production. We conduct a framed field experiment in northern Ghana to study how incentives and peer information may affect adoption. Incentives increase adoption, both while they are available and after withdrawal. There is no overall effect of peer information, but we do find evidence that information about long‐term adoption increased adoption, particularly when that information shows that yield gains have been achieved.
